This application is a continuation-in-part application under 35 U.S.C. §120 of U.S. patent application Ser. No. 12/569,784, filed on Sep. 29, 2009, entitled “Wonder Fabric”, and which claims the benefit of Indian Patent Application No. 2226/MUM/2009, filed on Sep. 24, 2009, entitled “Wonder Fabric”. The contents of the above applications are hereby all incorporated by reference in their entireties.

FIELD OF INVENTION

This invention generally relates to a novel textile material, more particularly wonder fabric, comprising of a see-through construction of plurality of yarns intersecting one another at certain angles, hydro-laminated thereof with pseudo yarns formed out of staple fibers and mechanical cross linking of yarns on at least one side under specific conditions thereof, resulting into a durable and multifunctional material suitable for home, upholstery and apparel textile applications. The process for production and apparatus thereof are also described.

BACKGROUND OF THE INVENTION

Traditionally, home and apparel textile fabric is produced through weaving or knitting technology. Weaving is the process of interlacement of plurality of yarns in vertical that is warp way direction with plurality of yarns in horizontal that is weft way direction. Knitting process requires only one yarn component. Using this yarn component, loops are formed followed by intermeshing of the same with the previously formed ones.

Each technology has its own application. Woven fabrics are strong and have advantage of drape and fall, are most commonly used for formal wear and most of home textile products. Knitted fabrics with their advantage of high extensibility/flexibility, softness and hugging tendency, are used for casual wear, undergarments and sometimes for sheeting applications in home textiles. Knitted fabrics lack in their strength and durability.

Both the traditional textile manufacturing processes are highly expensive and labor intensive. With day by day increasing competition, there is a high demand for cost reductions. On the other hand raw material cost is continuously increasing and labor cost is also increasing. This can be seen from the fact that Europe and America are almost out of traditional textile manufacturing business. Mostly, third world is having high concentration of this industry where low labor cost was the attraction. Year by year here also labor cost is steadily increasing and the solution of shifting of the traditional textile manufacturing base is not remaining cost advantageous.

Of all costs, raw material cost is the biggest contributor and it always contributes to the extent of 55% to 65%. Another important cost is operation cost which contributes to the extent of 10% to 15% of total cost.

From the human comfort point of view, in home and apparel textile, consumption of natural fiber, for example, cotton based products is high and is continuously increasing.

With fibers like cotton, impact of raw material cost on total cost is very high.

There is an intense relationship between yarn properties, fabric construction and fabric properties. Yarns should have certain minimum strength so as to withstand the stresses and strains of different types during weaving preparation and weaving and knitting.

On the similar lines, there exists an intense relationship between fiber properties and yarn properties. One needs to maintain certain minimum fiber properties to meet the required yarn properties. Most important of all the fiber properties is fiber length and strength. Longer and stronger fiber delivers stronger yarn. However, cost is directly dependent upon fiber length. This is how it puts a restriction on cost.

Also, it is very difficult to get all the fabric properties to the best level. Always it's a compromised approach followed for optimization of fabric properties. For example, wrinkle free 100% cotton fabric is on high demand. For this purpose cotton fabric is treated with wrinkle free finish. This brings down the tensile strength, tear strength, look and feel of the fabric will not be the same, fabric drape is also different. The wrinkle behavior improves with increased add-on of chemicals and with this increased chemical add-on, remaining fabric properties go bad. In this case, if one desires to have remaining properties also best, then there is a need for long and strong fiber meaning high cost.

With increasing demands for fabric functions like wrinkle free, odor free, antimicrobial, etc.; lot of chemical finishes are reacted with fibers in the fabric or are fixed with fibers using binders. Since they hamper fabric properties like strength, feel, etc., one needs to use expensive long and strong fibers. This adds further to the cost.

Various attempts for increasing throughput rates are made in fabric weaving and knitting. Dornier and also Pseudakoma, etc. are supplying weaving looms which can run at the speeds of 1000 to 1200 pick/minute. Mayer and Cie, Fukuwara are supplying circular knitting machines which can run at 80 to 100 r.p.m. Weaving looms with wider widths of 3.5 meter are also available which offer higher outputs.

On the similar lines, different high speed spinning technologies like Rotor spinning, air jet spinning and air vortex spinning are invented. However, ring spinning is still maintaining its dominance in yarn production. This is based upon its unique yarn structure most suitable for apparel and home textiles and also none of other spinning technologies are able to offer this yarn structure. However, ring spinning is the slowest among various yarn manufacturing technologies. Various attempts to improve its throughput rate are made and are still going on. With so many such efforts in entire traditional textile chain, one can expect some relief on operation cost.

With high speed textile machines and an increasing demand for high density fabrics, raw material quality demands are going high and there by the costs also are going high and advantage of lower operation cost is defeated.

Contrary to all this, consumer is looking for good products at lower costs.

Though ring spun yarn structure is the best, still there exists a limitation on fiber selection. One can not spin Ne 60/1 yarn from 20 mm fiber length. Similarly, Ne 60/1 yarn with strength of 16 Rkm can not run efficiently on high speed/wider Air Jet loom. This way technology has put a restriction on possibility of raw material value engineering.

Looking to today's scenario above, traditional textile technology has reached to its limit. Though one wishes for value engineering and meet market needs, it is very difficult. So there is a need to look at the subject from different angle. There is a requirement to redefine the fiber/yarn/fabric properties relationships so as to arrive at techno-economical solution.

In this direction attempts are made to work upon nonwovens. Nonwoven technology is another technology and method of producing fabrics. Using this technology, staple fibers and/or continuous filaments are bonded together to form a fabric. U.S. Pat. No. 6,736,916, U.S. Pat. No. 7,455,800, U.S. Pat. No. 7,452,834, U.S. Pat. No. 7,432,219, U.S. Pat. No. 4,805,275, U.S. Pat. No. 7,331,091, U.S. Pat. No. 6,103,061, and U.S. Pat. No. 6,063,717 disclose various ways of producing nonwovens. Nonwoven manufacturing involves web preparation, bonding, drying/curing, cutting slitting/winding.

There are various ways of bonding:

1. Mechanical bonding like malimo, needle punch and hydro entanglement;

2. Chemical bonding;

3. Thermal bonding; and

4. Combination of above

However, nonwovens are not perfect like woven or knitted fabrics and so far are not suitable for direct use in home and apparel textiles. They do exist in combination with woven or knitted fabrics. The best example is interlinings inside the garment.

Nonwovens lack in important aspects like look, drape and fall, abrasion and pilling resistance required for home and apparel textile. All these properties are not possible to be attained at the same time. For example, if bonding amount is improved so as to improve pilling resistance will hamper the hand feel and drape. The fabric becomes stiff. Another example can be that of fiber free movement if preserved, will generate good drape and feel. However, this will hamper the strength and pilling resistance. Various attempts have been made to improve nonwovens and make them suitable for apparel and home textiles. Still lot of work is going on in this direction.

European Patent No. 0896645 discloses lamination of two nonwoven fabrics using chemical adhesives. This invention relates to making nonwoven fabrics which are durable for machine washing and durable for other wet and hard use or abusive applications. The inventive fabrics retain the qualities of a spun laced nonwoven fabric which include low cost, comfort, drape ability, softness, absorbency, breathability and others while having the durability comparable to traditional knitted or woven fabrics. However, commercial success of this is limited. This fabric lacks in textile fabric look and feel/touch. Also, this fabric being originally a nonwoven lacks in pilling resistance. This fabric lacks in quick recovery from elastic deformations. If used in bottom weights, this limitation of the fabric results in cup formation at knees. This problem can be resolved through chemical adhesives, but then results in to making fabric very stiff and uncomfortable to wear. This fabric can go as the work wear that is worn on top of textile apparel fabric. At least today, we do not see this product on racks anywhere in the world meant for direct apparel and home textile application.

Another U.S. Pat. No. 3,498,874 reveals the attempt made to create a nonwoven material having a textile like look. Apertured nonwoven fabric which closely resembles woven fabric is characterized by fibers locked into place by tanglelacing that extends in a zigzag pattern along parallel bands interconnected laterally by fiber bundles defining rows of apertures between the bands. Preparation of the fabric from a loose layer of fibers, such as a random web, is illustrated by processing fiber layers on screen woven of heavier wires in one direction and 3 to 5 times as many finer wires per inch in the other screen direction. The fiber layer is traversed with fine, essentially columnar liquid streams from a manifold supplied with high pressure liquid to entangle the fibers. This product lacks in strength and durability required for its use into textile applications like home and apparel textile. Application of all such products is mostly limited to disposable products.

In U.S. Pat. No. 6,315,864, improved cloth-like base web is disclosed. In particular, the base web of the present invention has a cloth-like look and feel and improved absorbency. The base web is made by first hydroneedling a web containing pulp and/or staple fibers. A bonding material is then applied to at least one side of the web and the web is creped on at least one side. By combining a hydroneedling operation with a creping operation, a base web is produced that is strong, stretchable, very soft and absorbent. This also is a disposable product, suitable for hygiene applications.

Hydro-entanglement technology is the one which many researchers have tried to develop products which have a close resemblance to textiles. After understanding the potential of this technology, many attempts were made to use this technology to enhance traditional textile fabrics.

U.S. Pat. No. RE40362, U.S. Pat. No. 5,136,761, U.S. Pat. No. 4,967,456, WO/2005/059215, WO/1992/007984 disclose the attempts made for using high pressure water jets and treat face and back side of woven or knitted fabric thereby enhancing their dimensional stability, pilling resistance and mechanical properties like tensile strength. However, this is a kind of finishing process. This improves textile fabrics but at a high cost when compared to traditional textile finishing process. Therefore, we do not see its commercial advantage and application.

Reference can be made to U.S. Pat. No. 4,695,500 which discloses the use of hydro entanglement technology for stabilization of bandage woven fabric. The stabilized fabric is formed by covering one or both sides of the loosely constructed base fabric with a light web of the staple length fibers, and subjecting the composite material to hydraulic entanglement while supported on a porous forming belt configured to direct and concentrate the staple length fibers at the intersections of the yarns comprising the base fabric.

This improves the ease of bandage fabric usage. Bandage fabric feels soft and is more absorbent. However, this is a disposable product and also adds to the cost of basic product. Application is limited to bandage cloth which is used once and never washed and used again.

U.S. Pat. No. 4,145,468 discloses use of hydro-entanglement technology for manufacturing of synthetic leather substratum material. Composite fabric useful as a substratum sheet for artificial leather is composed of a woven or knitted fabric constituent and at least one non-woven fabric constituent. The nonwoven fabric comprises numerous fibrous bundles composed of a plurality of individual fibers arranged parallel to each other, and varying in the number of the individual fibers from which the bundles are formed, and numerous individual fibers independent from each other and from the fibrous bundles. The individual fibers and the fibrous bundles being randomly distributed and entangled with each other to form a body of nonwoven fabric, and the nonwoven fabric constituent and woven or knitted fabric constituent being superimposed and bonded together, to form a body of composite fabric, in such a manner that portions of the individual fibers and the fibrous bundles of the non-woven fabric constituent penetrate into the inside of the woven or knitted fabric and are entangled with a portion of fibers in the woven or knitted fabric constituent. This composite in its original format is not a durable product. Once coated with the suitable chemicals for making it synthetic leather, it becomes durable. This product is not suitable for apparel or home textile application.

Reference can be made to patent WO 2008/107907 A2. This invention relates to a composite fabric and a method and apparatus for manufacturing a composite fabric. In an embodiment composite comprises a base fabric made by weaving or knitting. A plurality of gaps is disposed in between the fibers of the yarns of the base fabric. A plurality of functional fibers is entangled in the gaps followed by swelling of the fibers, with predetermined retention to the yarns of the base fabric. This is a first attempt made to develop a fabric suitable for textile application. However, this composite has a limitation of wash durability. Also, there are limitations in entanglement of individual fibers with the fibers from yarns of base fabric. This poses a risk of entanglement of fibers from web amongst themselves and thereby resulting into problem of missed out entanglement between fibers from web and fibers from yarn of base fabric thereby resulting in delamination and poor durability and life. Also, it does not reveal great commercial advantage over the present textile fabrics.

The German company Freudenberg and the US company BBA Nonwovens did try to develop and introduce a 100% nonwoven fabric called Evolon using spun jet technology and splittable bi-component synthetic filaments for apparel textile application. Compared to other nonwovens, EVOLON was a much more durable product, processable on traditional textile dyeing and finishing machines. It also has a good drape.

However, this product was 100% synthetic and had a sueded leather touch which is not appreciated always. Also it lacked the traditional textile fabric look which people are familiar with. Also, it was expensive and did not get a commercial success.

As seen from prior arts and above, sufficient successful attempts are not made so far as to create an alternate to durable traditional textiles used for home, upholstery and apparel application. There is a need to relook at traditional textiles the way they are done today from the perspective of achieving required product attributes with ease of process and at lower costs.

The wonder fabric invention offers a solution required for today's traditional textiles. Through this invention, it is possible to deliver the right product suitable for home and apparel textile applications at costs lower than today's.

Unlike nonwovens or composites referred in prior art, wonder fabric so done is launderable and durable and processable just like traditional textiles.

This invention simplifies the traditional textile process and helps curtail cost. Woven or knitted fabric is manufactured with lightest possible construction to the extent that it is having a see through effect and is completely unstable. Required properties/attributes/functions are inculcated in the later stage during hydro-lamination with pseudo yarns and cross linking fibers in a cost effective manner.

This makes traditional textile process simple and cost effective. This also makes the final product cost effective. Wonder fabric can be dyed and finished using the same equipments and process as they are used for traditional textiles.

In one final step, this invention inculcates important attributes like high comfort, easy care or wrinkle free property, good recovery from creasing, clean and sharp look, smooth and tough surface and of course good wash durability required for apparel and home textile applications.

OBJECT OF INVENTION

The main object of this invention is to provide a multifunctional wonder fabric comprising of fabric element with see through and unstable construction which is hydro-laminated with pseudo yarns and cross linking fibers.

Another object of invention is to provide a cost effective method and process of manufacturing fabric suitable for home, upholstery and apparel textile application.

Yet another object of the invention is to develop a new method of creating pseudo yarns in the plurality of gaps among the yarns and entangling them strongly with the yarns from woven or knitted fabric, thereby creating a look very close to traditional textile fabrics used for home, upholstery and apparel textile.

Further, object of this invention is to redefine traditional relationship between count and fabric construction with fabric properties.

Yet another object of the invention is to provide a new method and process of inculcating the required functions or attributes in the openly constructed and unstable fabric.

It is also the object of the invention is to provide a launderable fabric with high durability.

SUMMARY OF INVENTION

In accordance with above objectives, the present invention provides a novel multifunctional wonder fabric suitable for sheeting, mattress/pillow shell and similar applications in home textiles. This fabric is also suitable for tops and bottoms, undergarments and similar applications in apparel textiles. This fabric is also suitable for curtains, furniture covers and similar products in upholstery.

According to present invention, the wonder fabric comprises an open fabric with see through and unstable construction of intersecting plurality of yarns together with pseudo yarns hydro-laminated thereby delivering a stable product with acceptable look and functions/attributes required for home, apparel and upholstery applications.

According to present invention, a fabric with see through and unstable construction is hydro-laminated with pseudo yarns on at least one side thereby inculcating properties like dimensional stability, strength and durability.

According to present invention, fibers which do not participate in the formation of pseudo yarns are cross linked with yarns of fabric thereby helps to inculcate properties like easy care/wrinkle free, recovery from creases and dimensional stability.

According to present invention, amount of entanglement depicts the textile feel, touch and behavior.

According to present invention, fabric is either woven or knitted and can be taken directly from loom or prior to dyeing or dyed or in finished form. The so hydro-laminated wonder fabric can be dyed and finished in the later stage in the same way like any other textile fabric.

DETAILED DESCRIPTION OF DRAWINGS

From FIGS. 1 and 2 one can see the pseudo yarns formed in the space between two consecutive yarns of the see through fabric component. One also can understand that fibers from these pseudo yarns and also external fibers entangle and create bonding between pseudo yarns and yarns of the see through fabric component.

In the SEM photograph as shown in FIGS. 4, 10, and 11 one can see the pseudo yarns formed in the space between two successive original yarns. For better clarity, these pseudo yarns are encircled and shown. In the SEM photograph as shown in FIG. 5, one can see the pseudo yarns. External fibers bonding these pseudo yarns are also seen.

In the SEM photograph as shown in FIG. 6, there are external fibers which bond the original yarns to each other. This helps guide and control original yarn movement in the fabric. Fabric properties are depicted accordingly.

FIGS. 3a-3b show the equipment configuration 300 used for the manufacture of this wonder fabric. This line has at least one fiber opening line with various opening, mixing/blending machines 302, 304, 306 and if cotton then cleaning machines 303. Thus opened and/or cleaned fiber material is fed to carding machine 314 through the card feeder 308. Here fibers are individualized and arranged in a particular manner as depicted by speeds and settings of rotating parts. For example, with proper planning and control of speeds and settings of doffer-transfer roll-random roll (not shown) and adjustment of condenser suction rate one can control fiber orientation in the machine direction, cross direction or can create a random orientation. Fibers so individualized are delivered on to fiber transport belt 318 in the form of a fiber web which is then transported 316 to hydro-lamination device 324.

The fabric with see through construction is delivered from a fabric roll 312 arranged behind the carding machine 314. Fabric is passed through the expander 310 for proper opening followed by proper tensioning through drafting rolls in the expander 310. So opened up fabric is supported/transported by guide rolls (not shown) to hydro-lamination device 324.

In the hydro-lamination device 324, the see through fabric is hit by at least one streams of high pressure water streams delivered through injectors 320 a, 320 b, 320 c, 320 d, 320 e, 320 f, 320 g, 320 h, 320 i. There may be a different number of injectors than shown. In addition, these injectors 320 a, 320 b, 320 c, 320 d, 320 e, 320 f, 320 g, 320 h, 320 i are found in the hydro-lamination divide 324, and at other points in the equipment configuration. At least one of the water stream strikes the fabric at an angle. Depending upon requirement, at least one water stream strikes the fabric in a direction in which fabric is moving or an opposite.

Selection of hydro-lamination parameters is guided by the final fabric properties required.

So treated fabric with relaxed and voluminized yarns is met with fiber web as shown in the FIG. 3a . Both now onwards are made to face successive steps of hydro-lamination.

Hydro-lamination is done using at least belt or perforated drums 322 a, 322 b, 322 c with suitable shells. These drums 322 a, 322 b, 322 c can also be found elsewhere in the equipment configuration 300. Shells depict the effective perforation area used and water rebounce.

During hydro-lamination, at least one water stream will strike the fibers and fabric at preset angle and direction from injectors or jet heads 320 a, 320 b, 320 c, 320 d, 320 e, 320 f, 320 g, 320 h, 320 i above. Fabric and fibers are also made to face at least one oscillating water stream. Also, fabric and fibers are made to face at least one high pressure water stream. These water streams are arranged and parameters are designed based upon properties required in the final product. Water streams are delivered by injectors 320 a, 320 b, 320 c, 320 d, 320 e, 320 f, 320 g, 320 h, 320 i as shown in the FIG. 3 a.

Remaining hydro-lamination parameters like jet size, jets/inch, jet length, vacuum, shell type, etc., are planned depending upon the properties required in the final product that is wonder fabric.

So formed wonder fabric is then passed on to dewatering device 326. This device removes physically held water by using vacuum.

Thus, dewatered wonder fabric is then passed through the dryer 328 for removing chemically held water. Wonder fabric so dried is finally wound on bobbins, at the winder 332. If necessary, before winding, it is slit in width wise direction to the pieces of required widths.

A fabric may be produced using a textile substrate that has either been pre-treated (OK Sample) as described here or an inferior fabric produced using a textile substrate not pre-treated (NOT OK Sample). The Flow Path Model where an OK Sample with the pre-treatment of the textile substrate at Drum 1 (FIG. 17A) and where a NOT OK Sample without the pre-treatment of the textile substrate at Drum 1 (FIG. 17B) are shown. This is demonstrated by the presence and absence of the two Drum 1 jet streams, where the Flow Path Model of the NOT OK Sample has “X” markings in the two Drum 1 jet stream rectangular boxes indicating the absence of the jet streams and hence the absence of the pre-treatment. The specific process route parameters chart further demonstrates the presence of the pre-treatment of the textile substrate for the OK Sample with the pre-treatment of the textile identified by the specific pressures for jet head (J.H.) 1.1 and jet head (J.H.) 1.2 of Drum 1 and the absence of the pre-treatment of the textile substrate for the NOT OK Sample without the pre-treatment of the textile shown by the lack of any pressures for jet heads 1.1 and 1.2. All of the other parameters in the production of the final fabrics were the same.

DETAILED DESCRIPTION OF INVENTION

The invention will now be described in detail, along with certain preferred and optional embodiments so that various aspects thereof may be more fully understood and appreciated.

The present invention provides a unique, multifunctional and durable textile material with a look acceptable for home textile, upholstery and apparel textile application having multiple advantages over prior art.

Here onwards, textile fabric with see through and unstable construction will be called as textile substrate as shown in FIGS. 15(a) and (b). As shown in FIGS. 4 and 5, at least on one side of textile substrate, pseudo yarns are formed. These pseudo yarns are entangled with textile substrate.

Textile substrate can be manufactured using weaving technology or knitting technology. Yarns those are used for manufacturing of textile substrate can be combed and/or carded yarns. Further, these yarns can be either ring spun or open end spun yarns or air jet yarns or air vortex yarns or friction spun yarns. Also, yarns spun from any other technology other than the one mentioned before can be used for manufacturing textile substrate. Also, these yarns can be monofilament yarns or multifilament yarns spun from synthetic polymer melts.

Yarns used for the manufacturing of textile substrate can be a single yarn or plied yarn. Also, these yarns can be with hard core or soft core.

Yarns used for manufacturing of textile substrate can be spun out of grey cotton or bleached cotton or dyed cotton or undyed manmade fiber or dyed manmade fiber or blends.

As shown in FIG. 6, the yarns from textile substrate are also entangled with the fibers. These fibers here onwards will be called as cross linking fibers.

Process of layering of fiber web on top side of textile substrate followed by entanglement of fibers amongst themselves thereby forming pseudo yarns followed by entanglement of pseudo yarns with yarns of textile substrate followed by entanglement of cross linking fibers with fibers of yarns from textile substrate and pseudo yarns will be called as hydro-lamination.

Hydro-entanglement device usually consists of at least one pressurized water stream delivered by injector through jet strip on to material being supported by belt or drum with or without shell. It is common that water jets from injector point towards the drum centre.

Material so formed, is further treated with chemicals for pre treatment, dyeing and/or printing and post treatment. The final product so delivered and as shown in FIG. 8, 9 and dyed/bleached fabric as shown in FIGS. 12(a) and 12(b), 13(a) and 13(b) and 14(a) and 14(b), now onwards will be called as wonder fabric or multi-purpose fabric.

Textile substrate is taken directly from weaving machine or knitting machine. Also, it is possible that textile substrate is dyed and processed before hand.

In an embodiment, the textile substrate is subjected to at least one high pressure straight jet stream. Further, the said textile substrate is also subjected to at least one jet stream that strikes at an angle. Another embodiment is directed to the pre-treatment of a textile substrate where a straight jet nozzle is first applied to a textile substrate and followed by an angled jet nozzle. Yet a further embodiment relates to at least one high pressure jet stream. In a preferred embodiment, a textile substrate undergoes at least two jet streams where the second jet nozzle applies a high pressure jet stream to the textile substrate. The second high pressure jet stream has a pressure ranging from at or about 100 bar-at or about 400 bar, at or about 150 bar-at or about 250 bar, and at or about 180 bar. The application to a textile substrate, or to yarns of a textile substrate, of at least two jet streams, comprising at least one straight jet nozzle and at least one angled jet nozzle, results in combing and stripping actions. This may also result in partial entanglement of fibers from component yarns. The entanglement levels can be controlled by varying the jet stream pressures, jet nozzle types, and order of the application of jet streams during entanglement. Without being bound by theory, a higher pressure results in more random entanglement and application of a jet stream through an angled nozzle results in random entanglements as well. The speed of a textile substrate and/or web fiber before or after pre-entanglement is generally the same as shown in FIG. 18A. As required, direction of fabric movement is adjusted in such a way that jets and textile substrate move in the same direction or oppose each other. In either case, yarns from textile substrate are subjected to combing/stripping action and thereby resulting in to rearrangement of fibers in the yarns and making it suitable for serving as the support material during formation of pseudo yarns. This also results in to random fiber entanglements resulting in to yarn structure which can not be untwisted or disintegrated easily. This also results in to partial entanglement of fibers from component yarns. As per requirement, the entanglement level can be controlled thereby improving fabric properties.

By selecting proper jet stream parameters like jet size of 0.079 mm to 0.14 mm, with suitable energy when strikes textile substrate, suitable hand-feel and touch are created.

In a preferred embodiment, the invention provides a multipurpose wonder fabric suitable for home textile, upholstery and apparel textile application comprising at least one textile substrate with see-through and unstable construction, hydro-laminated with pseudo yarns so formed by hydro-entangling fibers on at least one side of textile substrate. The wonder fabric will have at least one textile substrate hydro-entangled with cross linking fibers at least on one side.

The said textile substrate is manufactured using weaving technology or knitting technology. Further, textile substrate can be manufactured from natural fibers or manmade fibers or their blends. The said textile substrate is constructed with yarn counts in the range of Ne 1 to 160, preferably in the range of Ne 5 to 160.

Pseudo yarns or web fibers entangled among themselves in gaps of the pre-treated textile substrate assist in producing a stable final fabric. Pre-entanglement of fibers of a web create the necessary strength in the web.

However, one embodiment relates to a final jet stream as applied to the web of fibers layered on a pre-treated textile substrate may have a jet pressure that is less than at least one or a plurality of prior jet streams. The successively increasing jet pressures assist in web disintegration and slipping away of fibers in the spaces between yarns, followed by rolling around of fibers in the same space being guided by yarns of the pre-treated textile substrate, thereby resulting in the formation of pseudo yarns or pre-entangled web fibers entangled among themselves in gaps of a pre-treated textile substrate.

Another embodiment further comprises post-production modifications. After hydroentanglement of the pre-treated textile substrate and the pre-entangled web of fibers, the so produced multi-purpose fabric may undergo any one of, or a combination of the following post-production steps, including:

While the invention has been explained with reference to the specific examples of the invention, the explanation is illustrative, and the invention is limited only by the appended claims (after explaining the invention).

Examples Example 1

0.1 mm jet with 23 jets/inch arranged in single row strikes the web at pressure of 50 bar there by creating fiber entanglement level resulting in to tensile breaking load of 4.5 Newton/meter of width of web in machine direction and 1.7 Newton/meter of width of web in cross direction.

This fiber web then is subjected to a plurality of water jets designed with parameters suitable for forming pseudo yarns on the surface of the textile substrate. In this case, textile substrate works as support for fiber web. Textile substrate guides and facilitates rolling around of fibers from web there by making these fibers to entangle among themselves and form pseudo yarns.

Example 2

Textile substrate with fabric cover factor of 14 is layered with cotton fiber web and whole structure is subjected to high pressure water jet streams with jet description of 0.1 mm/23 jets/inch, 0.1 mm/40 jets/inch and 0.1 mm/40 jets/inch results into maximum fiber rolling and pseudo yarn formation as shown in FIG. 4, with very few traces of fibers on the bottom side of textile substrate.

Above phenomena is also influenced by fiber properties like polymer, fiber length, stiffness, diameter and surface friction. Web properties like fiber orientation, fiber individualization also influence the above phenomena.

Above structure is then subjected to at least one high pressure water jet stream. Fibers from pseudo yarns entangle with fibers of yarns from textile substrate. Water jet parameters are selected according to the balance between strength and product stiffness.

Example 3

Textile substrate with 80 g/m2 and pseudo yarn structure with 35 g/m2 when subjected to high pressure water stream with 0.1 mm jet size, arranged in single row results into pilling resistance of 5.0 and fabric stiffness acceptable for sheeting application.

Out of various attributes of textile fabric meant for home and apparel textile, first and foremost attribute important for any consumer is look of the fabric, and then comes feel. This is followed by the strength and durability. With time and increasing awareness of safety and hygiene, attributes like antimicrobial, odor kill, fire retardancy, etc., are becoming more and more important.

On the other hand, cost is also important aspect. Those products which deliver required look and attributes at nominal cost will have a surety of sale. This is known as value for money.

As described above in the background of invention, raw material cost is the biggest of all the components of cost. On account of technological limitations of spinning and weaving or knitting, technically and commercially important raw material properties like fiber length, strength, etc., can not be dropped below a particular limit. Therefore using this approach of value engineering by use of inferior raw material, costs can not be reduced drastically, for example; to the tune of 15 to 50%. Also, there is a risk of overall drop in operation efficiency. This for sure will deliver inferior product.

In this invention, a different and unique approach is followed. Textile substrate is designed and constructed with very open and see through construction there by reducing weight of the textile substrate to the tune of 15 to 50%. This brings down the cost drastically to the level of up to 50%. However, this textile substrate in it's as it is form is not stable and also is not having a look and other attributes acceptable for home, upholstery and apparel application.

This invention uses this textile substrate as a support for the entanglement and formation of pseudo yarns. The fibers from web once subjected to high pressure water jets, prefer to slide down into the gaps. These fibers prefer to entangle among themselves first till they achieve a certain packing density. This gives rise to formation of pseudo yarns. So formed pseudo yarns along with textile substrate, when subjected further to high pressure water jets, entangle through their fibers with the fibers from yarns of textile substrate.

The remaining fibers which do not roll down and become part of pseudo yarns entangle with the fibers from yarns of textile substrate. This way they cross-link among the yarns of textile substrate. This also depicts the fabric properties. By using the process defined in this invention, one can achieve durable press rating of at least 3.0 meaning wonder fabric so done is easy care, by default.

Phenomena described above also results in to introducing dimensional stability in the unstable textile substrate.

Example 4

Textile substrate with Ne 40/1×Ne 40/1 and 100×68 threads/inch in warp and weft respectively and web of 26 mm cotton fibers, when operated through this invention results into residual shrinkage of less than 4.0% in warp and less than 2% in weft way direction. This is in contrast to the original shrinkage potential of 12% in warp and 6% in weft way direction as tested in textile substrate.

Apart from look, pseudo yarns so formed and entangled with yarns from textile substrate depict the tensile strength, tear strength. One can find the improvement in tensile strength by at least 25%. Tear strength also improves by at least 8%.

Example 5

Textile substrate with Ne 40/1×Ne 40/1 and 107×38 threads/inch in warp and weft way direction when run along with cotton fiber web made out of 24 mm and 22 g/tex strength through findings of the invention gives breaking load 90 lb (+50%) and 34 (+20%) lb when tested for tensile strength. This also delivers tear strength of 4.5 lb (+35%) and 3.5 lb (+15%) in weft way direction.

Both pseudo yarn formation and entanglement with yarns from textile substrate along with cross-linking fibers entanglement with yarns from textile substrate result in to 15 to 35% improvement in resistance for seam slippage.

This invention not only blooms out yarns from textile substrate but also introduces high number of pores and continuous capillaries there by the wonder fabric delivered is highly absorbent and is capable of quick transportation of moisture through capillaries.

Example 6

Textile substrate with Ne 20/1×Ne 20/1 and 45×25 threads/inch along with cotton fiber pseudo yarns when treated using findings of the invention, wonder fabric so delivered possesses the absorption rate of less than 1 second.

Vertical wicking test shows the attainment of 13 cm in 30 minutes. This implies that wonder fabric so done is highly comfortable to wear.

During hydro-lamination, wonder fabric is subjected to at least one oscillating high pressure jet stream there by inculcating look features.

Wonder fabric so formed is also subjected to at least one high pressure jet stream which strikes the hydro-laminated surface at an angle there by inculcating durability features.

The invention provides the line configuration for the manufacture of multi-purpose wonder fabric comprising of opening line for opening of fibers in bale or similar form into small fiber tufts, carding machine for individualization of fibers and form the web with suitable fiber orientation, transport arrangement for web up to hydro-lamination device, fabric unwinder for proper unwinding of fabric, expander and pre-tensioning roll for expanding and controlling fabric width and do not allow formation of creases, hydro-lamination device for formation of pseudo yarns, their entanglement with yarns of textile substrate, cross linking of fibers with yarns of textile substrate, combing through and stabilization of yarns from textile substrate, dewatering device for removing physically held water, dryer for removing chemically held water and winder for winding of so formed wonder fabric. For apparel, home textile and upholstery application, it is processed through traditional textile processing machines. For technical textile and upholstery application, it is processed through coating and/or lamination machines.

Opening 1605 and carding 1610 of fibers and form the web 1615         with desired web properties.     -   d. Overlapping 1635 so formed web on the top of one of the sides         of the textile substrate 1630, supporting web on textile         substrate 1635 and subject both to at least one or plurality of         high pressure jet streams 1640, slipping off fibers 1645, and         rolling the fibers 1650, thereby forming pseudo yarns, entangle         them with yarns from textile substrate and also cross link the         remaining fibers with the yarns from textile substrate 1655,         thereby delivering wonder fabric with desired properties, and         subjecting the pseudo yarns and textile substrate to high         pressure water jets 1660.     -   e. So formed wonder fabric is dewatered 1665 using dewatering         device followed by drying 1670 using dryer.     -   f. Dried wonder fabric is then wound 1675 on to bobbins or rolls         by winder.     -   g.

Example 10

From the following table, one can depict that wonder fabric manufactured using findings of invention exhibits a very good dimensional stability. It is interesting to note that fabric is stabilized using fiber rearrangement in the yarns of textile substrate followed by further higher level of entanglement among fibers in these yarns. The traditional process of crimp interchange and rearrangement in thread density for fabric stabilization is not used here in this invention. Cross-linking fibers also entangle with fibers from yarns of textile substrate and there by help stabilize the structure of wonder fabric. The level of entanglement is controlled to a level there by attaining acceptable stiffness and feel of wonder fabric so manufactured.

Example 15: Quality Testing of Washability

Test Method: AATCC-135

A fabric sample produced with a pre-treated textile substrate (OK Sample) and without a pre-treated textile substrate (NOT OK Sample) underwent various quality testing, including washability. After 3 washes as performed per guidelines of AATCC-135 with a machine wash at 105° F., normal cycle followed by tumble dry at medium mode of both the OK sample and the NOT OK sample resulted in a dimensional change percentage of 6% in the warp direction and 6.4% in the weft direction of the NOT OK sample compared to the OK sample which had a dimensional change percentage of 3.8% in the warp direction and 2% in the weft direction. High residual shrinkage found in the NOT OK sample compared to that of the OK sample was concluded to be due to the absence of the two jet heads used in the pre-treatment of the textile substrate.

The unwashed and washed fabric pictures in FIG. 19 show the wrinkling behaviors between the two fabrics. As can be easily seen, the NOT OK sample has more wrinkles for both the Before Wash (B) and After Wash (D) samples as compared to that of the OK sample, where Before Wash (A) and (After Wash (C) samples have fewer visually noticeable wrinkles.

Example 16: Quality Testing of Pilling

Test Method: ASTM D 4970

Pilling, which is caused by a fiber migration from the fabric surface as the fabric rubs against itself or another fabric or even the skin, was also tested on the final samples (i.e., OK Sample and NOT OK Sample). The severity of a pilling problem is related to fabric construction and/or fiber type. For closed weave fabrics with high bonded fibers, pilling will be less. Weaves with loose bonded fibers have fewer binding points, so pilling will be greater.

Each of the OK Sample and NOT OK Sample were tested at 100 cycles. A pilling grade 4 means superior (i.e., less pilling) and 1 means worst (i.e., more pilling and fuzziness). Though a pilling numerical grade difference of 0.5 may be thought to be insignificant to laypeople, comparatively high pilling formation indicates that a fabric is inferior which is clearly visible after washing the sample.

On a Pilling Grade scale of 1 (worst) to 4 (superior), the Pilling Grade of the NOT OK Sample was 2 (i.e., deteriorated as compared to before washing. After washing, the binding of fibers started to loosen further). While, the Pilling Grade of the OK Sample was 3.5 (i.e., no deterioration of the fabric structure and fiber bonding). From FIG. 20, it is clear that the NOT OK Sample (B) has several pills compared to that of the OK sample (A).

Samples that were not manufactured as claimed easily delaminated. The comparative study disclosed in the Examples demonstrated that the NOT OK Sample was found to easily delaminate as shown by the separation of the layers in the bottom right corner of the NOT OK Sample of FIG. 21(A). Whereas, the OK Sample had the appearance of a single fabric with sharp edges that did not delaminate as shown in FIG. 21(B). The NOT OK Sample is more wrinkled and thus easier to delaminate, while the appearance of the OK Sample is satisfactory and without any delamination issue.

As is understood by those in the textile art, increasing jet stream pressure increases the entanglements thereby resulting in stronger materials. The multipurpose fabric was produced using a variety of water jet streams with several high pressure jet streams. FIG. 22 shows a NOT OK Sample both (A) Before Wash and (B) After Wash, which was produced using a modified method with an increase in jet stream water pressures. They were greater than the corresponding jet streams of an OK Sample manufacturing method by about 5 pressure bars for at least 3 jet heads, i.e., for example, J.H.-3.1, J.H.-3.2, and J.H.-4.1. However, even with the increased water pressures that were applied to both the final product comprising a textile substrate (without pre-treatment) and the web of fibers, the NOT OK Sample still resulted in an inferior final fabric as shown in the Before Wash (FIG. 22A) and After Wash (FIG. 22B) compared with the OK Sample Before Wash (FIG. 19A) and After Wash (FIG. 19C).
